Hashimoto’s symptoms may be mild at first or take years to develop. The first sign of the disease is often an enlarged thyroid, called a goiter. The goiter may cause the front of your neck to look swollen. A large goiter may make swallowing difficult. Other symptoms of an underactive thyroid due to Hashimoto’s may include:
- Weight gain
- Fatigue
- Paleness or puffiness of the face
- Joint and muscle pain
- Constipation
- Inability to get warm
- Difficulty getting pregnant
- Hair loss or thinning, brittle hair
- Irregular or heavy menstrual periods
- Depression
- Slowed heart rate
Because the symptoms of Hashimoto’s thyroid may be similar to those for other medical conditions, it is important to see your doctor for a diagnosis.
